Hanoi with children: one train ride, one green pause

The crucial distinction for Line 3 is between the operating elevated Nhon–Cau Giay section and the project name that includes Hanoi railway station. A government report from May 2026 described the underground section as under construction; a projected opening is not proof it has opened. The operator also displays future network routes, including an airport-related line. Do not turn that planning line into a claim that a metro train currently reaches Noi Bai. For Line 2A, compare your trip with the Cat Linh–Ha Dong corridor rather than expecting direct service to every Old Quarter sight.

The national tourism authority describes paved paths and local exercise in the park. That everyday use is part of the interest: you can spend time observing the relationship between a large green space, the water and the surrounding city rather than chasing a sequence of exhibits. For orientation, distinguish the park’s Bay Mau Lake from Thien Quang, which appears in the wider walking route. They can complement each other, but they are not two names for the same lake.

National tourism material presents West Lake as a notable Hanoi landscape and includes the area in walking ideas. Tran Quoc Pagoda is a recognised religious landmark associated with the lake setting. Seeing a landmark from a public space and entering it are separate decisions: a walking suggestion does not confirm opening arrangements, admission or permission to photograph worship. Keep any visit to a sacred site as an optional, separately checked element rather than a condition of enjoying the lake.
